Thankyou very much, sir. I had a 'foggy' understanding, I now enjoy a clear understanding (clarity, is a nice place to be).

@@WirelessLANProfessionals I see there is a transcript of the video as well on that site. That is very nice. I am going to laminate that. I fear that the 802.11ax MCS chart along with the HT, and VHT chart will not be pocket size with normal readable font (for over 40+ year old) [physical version, not digital version].

@@gabrielreyes3492 I realized I hadn't linked the PDF version to the blog post - it's up there now under the jpg image of the table. Also, we have our field notebooks for sale on the store that have the MCS Table as well as other handy charts - not sure if you've seen those yet.

On Specifications of some APs: I find under the Reception Sensitivity this: ex: 11a 6Mbps:-97dBm, 11a 54Mbps:-79dBm 11ac VHT20_MCS0:-96dBm, 11ac VHT20_MCS11:-66dBm 11ac VHT40_MCS0:-94dBm, 11ac VHT40_MCS11:-63dBm 11ac VHT80_MCS0:-91dBm, 11ac VHT80_MCS11:-60dBm 11ax HE20_MCS0:-95dBm, 11ax HE20_MCS11:-63dBm 11ax HE40_MCS0:-92dBm, 11ax HE40_MCS11:-60dBm 11ax HE80_MCS0:-89dBm, 11ax HE80_MCS11:-58dBm 1- why mentioning 11a,ac,ax since HT, VHT, HE are mentioned? both indicates the same thing from my understanding. 2- how come there is VHT with MSC11? From my understanding VHT is iteration of 0 to 9 and HE is iteration of 0 to 11 (with each iteration the spatial stream increases +1) 3- The information above don't mention the spatial streams so you can't really tell which Mbps it corresponds to. Thank you so much

Thank you so much for the video. I’d like to know if there is a way to set the modulation regardless of the PHY (or rssi) ?

Thank you so much for the video. In 802.11ax table, there is no mention of SNR. Is there a way to map SNR to code rate in 802.11ax? Thanks.

Hi, Great video. Is it possible to obtain a MCS value from a win 10 device or application?
@KeithParsons
@KeithParsons 3 роки тому
Not directly - you can get the current data rate, then reverse engineer from an MCS table by looking up the data rate. But sometimes, there are multiple possible combinations of MCS that give the same data rate. So you might have to guess on Spatial Streams to narrow down your result. This is another reason I love using macOS since it freely and easily reports MCS.

Is there any relation between MSC and Tx power?
@traver1965
@traver1965 3 роки тому
I am a novice here but I think the answer is no. You can uphold a higher MCS without having taking into account TX/RX. But I think a lot of vendors only looks at TX/RX in matter to choose the best Access-point. Sadly
@andrewparamonoff
@andrewparamonoff 3 роки тому
@@traver1965 I am asking because I've seen lot of vendors who published some dependance MCS-Tx power-Rx sensitivity in datasheets. For example, Aruba and Mikrotik always do that. For example, for Mikrotik LDF5 there are such references: for 6 Mbps max Tx is 25 dBm, Rx sensitivity is -96 dBm: for MCS7 max Tx is 19 dBm, Rx sensitivity is -75 dBm. I understand why you need better signal to work with more complex constellation, but why you can't transmit "harder" for them - I don't quite understand.
